层次分析法在中水工程工艺方案优选中的应用 摘 要 随着我国经济快速、持续、稳定发展，城市化进程的加快，城市规模扩大， 城市人口迅速增长，城市水资源短缺与城市发展的矛盾加剧，水体污染严重， 城市水资源“开源”成本和“治污”成本日益提高。城市中水系统同时具备“开 源”和“治污”两种功能，具有重大的经济效益、社会效益和环境效益。建筑 中水系统是城市中水系统的重要组成部分，具有距离中水用户近、水质单一、 易于实施等优点，因而更现实和可行。 为保证中水工程在建设方案选择时的合理性及决策的正确性，需要对中水 工程的工艺方案进行优化选择。中水工程的工艺方案优选是一项复杂的系统工 程，涉及到经济、环境和社会等诸多方面。以往的中水工程工艺方案优选主要 考虑的是经济效益，而忽略了其他重要因素的影响，因而存在着一定的片面性。 本文从经济指标、技术指标、管理指标、水质指标和社会影响五个方面选择 了 16 项有代表性的指标，根据层次分析法建立中水工艺方案优选模型，并将该 模型应用到实际的案例上，相对于单一的经济评估模型更加合理和全面。 应用表明，本模型具有科学性和应用性。 关键词：中水工程；指标体系;工艺方案优选；层次分析法 Application of analytic hierarchy process for selecting optimal process scheme of reclaimed water project ABSTRACT Along with our country economy rapid, sustained, stable development, the acceleration of urbanization, urban scale, the urban population growing rapidly, and city of city development the shortage of water resources and the conflict intensifies, serious water pollution, municipal water tap new sources of supply costs and pollution treatment cost is increasing day by day. City recycle-water system along with tap new sources of supply and pollution treatment two functions, it has great economic benefits and social benefit and environmental benefits. Building recycle-water system of urban water system is an important component part, have nearly, water quality water users from onefold, easy to implement wait for an advantage, thus the more realistic and feasible. To ensure the reclaimed water project construction scheme selection the correctness of rationality and overall decision-making in engineering, must the optimization process scheme. The processing plan of water project is a complicated system engineering, involves the economic, social and environmental aspects. Before the water engineering plan optimization based mostly from the economic efficiency, ignoring other factors exist certain one-sided. This research from the economy, technology, management, water and social impact five aspects chose the typical 16 optimizing targets, based on AHP process
